I'm working on the following problem set from codingbat.com
http://codingbat.com/prob/p107863
Given 3 int values, a b c, return their sum. However, if one of the values
is 13 then it does not count towards the sum and values to its right do not
count. So for example, if b is 13, then both b and c do not count.
lucky_sum(1, 2, 3) → 6
lucky_sum(1, 2, 13) → 3
lucky_sum(1, 13, 3) → 1
The solution I came up with was -
def lucky_sum(a, b, c):
t = 0
for ints in (a, b, c):
if a == 13:
t = b + c
elif b == 13:
t = a
elif c == 13:
t = a + b
else:
t = a + b + c
return t
However the following tests fail
lucky_sum(13, 2, 3) → 05X lucky_sum(13, 2, 13) → 015X lucky_sum(13,
13, 2) → 015X
Can anyone show me an example where all test are success?
